To all/whom it mag concern:

Providence, in the county of Providence and State of Rhode Island, have invented a new and useful. Improvement in Can-End-Seour-f .ing Machines, of whichthe following 1s a 1 1 specification.

. This invention relates -.to certain new and useful mprovements in cancend securing machines and pertains more particularly to a'inachine for securing the bottoms or. tops of cans or containers to the cylindrical can bodies.

The invention has for itsohjectto produce asmachineof .this type in wh ch the operator loy successive and practically continuous i movement of a single tool carrier can easily andexpeditiouslyeffect.thesuccessiveopera;

The'tools are jin the form of {wheels and are mounted on loolts 14L which extend through alined perforations "in the disks? and 8 and are secured in positionbythenuts 15.

"ReferringtoflFig. 1 it will he seen that the tool carrier '5 has i five wheels. thereon arranged in the'successive order now to be de scribed. "Wheel .16 has a circular flange 17 of uniformthiclrness and a smooth peripheral :portion' 18jwhich projects upwardly from thefflange" l7,;the thickness of the "flange l'l beingjsuflicient so as to admit the Ilatterfi'n thespace4 of thefcan carrier 1 as depicted in Fig. 6. Wheel I9 hasafiange 20 similar to {flange 17 and anupwardly proeating portion 21 which is provided with a a; downwardly converging peripheral part 22. 1 Fig. .6 is a similar iew showing the parts in the. second step and-the tool .for eflfecting (The lfiext wheel 23 has a circular flange 24 an upwardlyfextending part 25 formed withagroove26 thatis ofconcaveoutline.

The next wheel 27 'hasa fla-nge 28 and an upwardlyprdjecting part'29 formed with an outwardly fflared or converged peripheral clilar .flange 32v and an upwardly projecting circular part 33 formed with iaconcave groove. 3i similar to groove26 but of greater width .thanthe latter. p p i TThe' tucker =w11eel @35 is; provided with a circular part having a concave peripheral groove 36, the tucker wheel being rotatably mounted on one end of a curved arm 37 which latter is pivoted at 38 to the outer end of a substantially vertical arm 39. Arm 39 is pivoted at 40 to the bracket 41 which latter is carried by a member L2 suitably secured to the frame of the machine. The tool carrier 5 is formed with a radial perforation in which is secured a rod 43 providing a handle so that the operator may turn the tool carrier 5 in a manner later described. The tool carrier 5 is pivoted to the bracket 41 as shown in Fig. 2.

In operation the body of the can G and an end thereof B is furnished from the press as shown in Fig. 5, the parts being placed on the carrier 1 and clamped to the portion 3 thereof as shown in Fig. 5. The carrier 1 is now caused to rotate at a high speed, the operator next grasping handle 43 so as to turn the carrier 5 to bring the wheel 16 into operation, the peripheral part 18 of the wheel 16 engaging the flared edge F of the bottom B as shown in Fig. 6 so as to move said edge F inwardly to be turned into the upright position of Fig. 6. It will be noted that in this step as well as in all of the succeeding steps the flanges 17, 20, 24, 28, and 32 have their upper faces providing supports engaging the flange F of the can bottom B, so as to prevent downward movement of the can C or the end B thereof. After the parts have been rolled into the position of Fig. 6, the operator then turns the carrier 5 to bring wheel 19 into operation. The flared part 22 or wheel 19 bends the flange F of bottom B inwardly by contact with the inclined part 2 as depicted in Fig. 7. The operator now again turns carrier 5 bringing the wheel 23 into operation the latter depressing the flange F as shown in Fig. 8 between the base of the part 25 of wheel 23 and the upper face of flange 2& thereof. Upon further turnin of the carrier 5 by theoperator wheel 2 is brought into operation, the upwardly flared peripheral portion 30 of which turns the flange F upwardly at an angle as depicted in Fig. 9. In this operation the flange F of the bottom B sometimes will spring outwardly or next to the can body C. In such cases the tucker wheel 35 is brought into operation by lifting the arm 37 into the position of Fig. 4 unti the outer face of the tucker wheel 35 contacts with a periphery of the can body C, further lifting of the arm 37 causing depression of the wheel 35 and contact with the flange of the bottom B so as to bend same in place as shown in Fig. 4:. The finishing wheel 31 is now brought into operation rolling the two flanges, i. 0., F and G into intimate contact so as to make an air tight relationship of the parts as shown in Fig. 10.

The wheel 31 can obviously be of any desired configuration so as to give the parts any desired final shape other than that shown in Fig. 10. The peripheral part 31 of wheel 31 could also be knurled so as to knurl the bead at its periphery. Since the carrier 5 is given a practically uninterrupted movement by the operator, the operation is practically one continuous motion of the handle or rod 13.

By referring to Fig. 4 it will be apparent that the tucker wheel 35 has a compound movement, namely, it can move vertically in both directions as well as horizontally toward and away from the can. It will furthermore be apparent that the tucker mechanism is selectively operable and when operated its point of operation is in advance of the crimping wheels so as to not interfere with the latter in any way whatsoever. It will furthermore be noted that "the parts could be positioned with the carriers 1 and 5 vertical, instead of horizontal, as shown.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a machine for securing can ends to the bodies thereof, a can carrier, a rotatable tool carrier adjacent thereto, means to rotate the tool carrier, a series of wheels ro- 'plvoted to an end of the first arm, and a tucker wheel mounted 011 the free end of the second arm.

2. In a machine for securing can ends to the bodies thereof, a can carrier, a tool carrier, crimping means on the tool carrier, a substantiallyvertical arm, means to pivotally support said arm from the lower end thereof to allow same to swing bodily into and out of the plane of the can carrier, a second arm traversing the upper end of the vertical arm and pivoted at an intermediate point to the vertical arm so as to lie in one position above the pivotal point of the vertical arm, a tucker wheel carried by the front end of the second arm, and a handle on the rear end of the second arm.

3. In a machine for securing can ends to the bodies thereof, a can carrier, seaming means, a pivoted element movable toward and away from the seaming means, a second element pivoted to the first element so as to move with the first element and also independently of the first element, a tucker wheel carried by an end of the second element, and a handle on the second element to move both elements in unison or the second element independent of the first element.

4:. In a machine for securing can ends to the bodies thereof, a can carrier, seaming means, an element pivoted at one end so as to be bodily swingable toward and away from the seaming means, a second element pivoted between its ends to the opposite end of the first element, and having a free end, and a tucker wheel carried by the free end of the second element, the opposite end of the second element forming whereby to oscillate the second element relative to the first element, or to move both elements in unison.

5. In a machine for securing can ends to the bodies thereof, a can carrier, a tool carrier, crimping means on the tool carrier, an

a handle arm, means to pivotsaid arm to allow an end thereof to swing into and out of the plane of the can carrier, a second arm, means to pivotally connect the second arm to said end of the first arm, and a tucker wheel on an end of said second arm.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
